Teach your students to calculate fractions of 100 using a number line model.

Allow your students to explore the pros and cons of different strategies used to find the area of rectangles. Use this as a stand alone lesson or as a pre-lesson for the Multiplication and Area in the Community Garden lesson.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Students will begin to calculate volume of different rectangular prisms using base ten cubes and then transition to using the formula V = L x W x H. Students will then practice using the legendary fifth grade activity, Cootie Catchers.

Your young scientists will have tons of fun visiting measurement stations and using tools to measure various objects. They'll even be able to create posters at the end of the activity.

Get your students synthesizing various subtraction strategies as they work with a partner to solve word problems. This lesson can be used alone or with the lesson plan Show Me the Money! Two-Digit Subtraction.

Look out! Measurement is all around us! In this lesson, students will learn about measuring tools and how to use them. Students will work cooperatively on a fun measurement hunt, exploring and applying concepts of measurement using inches.

Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.

Help students color-code their way to multiplying fractions! Students will learn how to multiply fractions using area models. Use this lesson on its own or use it as support to the lesson Area Models and Multiplying Fractions.

Area models are building blocks to more complicated multiplication and division. Use this lesson to refresh students on the relationship between multiplication and area to prepare them to use the area models strategy with larger numbers.

Start a dialogue around area models! In this lesson, encourage students to ask questions as they multiply using area models. Use this lesson on its own or as support to the lesson Area Models and Multiplication.
